The study of the oxidation of organic compounds at oxide-covered transitionmetal electrodes has been the subject of a number of recent papers 1-6. These studies have both theoretical and practical importance.
The study of the oxide-covered nickel electrodes may serve as a model to the elucidation of some kinetic and mechanistic problems of the reactions occurring at oxide-covered electrodes in general. In our present paper an attempt is made to call attention to some questions which seem to be unsolved in connection with the role of the nickel oxide layer in the oxidation reactions taking place at oxide-covered nickel electrodes.
The scheme of the oxidation process given by Fleischmann et al. 1 is as follows:

The oxidation of nickel, Ni with 0.5% Cu, Mu or Gr and with 2.5% Cr is investigated. Deviations from the psrabolic law in the case of pure Ni c8n be attributed to "8geing" effects in t,he oxide layer, and at temperatures above 950°C to the formation of a seoond layer under the first formed. Both Ni-
## Abstract This paper demonstrates for the first time, successful electrocatalytic oxidation of electroactive estrogenic phenolic compounds (EPCs) at a nickel‐modified glassy carbon electrode (Ni‐GCE). The electrode was evaluated in terms of electrocatalytic activity, sensitivity, linear dynamic r
Sulphite (5.0 X lo-'-5.0 X lo-' M), ascorbic acid and other compounds are oxidized by potassium iodate in dilute sulphuric acid; the production of iodide is monitored by an iodide-selective electrode. The time needed for a 40-mV potential change is inversely proportional to concentration. For sulphi
